Configuration procedure

1. Assign an IP address and subnet mask to each interface according to Figure 17. (Details not

shown.)

2. Enable IP multicast routing, PIM-DM, IGMP, and IGMP proxying:

# Enable IP multicast routing on Router A, PIM-DM on Serial 2/1, and IGMP on Ethernet 1/1.

<RouterA> system-view

[RouterA] multicast routing-enable

[RouterA] interface serial 2/1

[RouterA-Serial2/1] pim dm

[RouterA-Serial2/1] quit

[RouterA] interface ethernet 1/1

[RouterA-Ethernet1/1] igmp enable

[RouterA-Ethernet1/1] pim dm

[RouterA-Ethernet1/1] quit

# Enable IP multicast routing on Router B, IGMP proxying on Ethernet 1/1, and IGMP on Ethernet

1/2.

<RouterB> system-view

[RouterB] multicast routing-enable

[RouterB] interface ethernet 1/1

[RouterB-Ethernet1/1] igmp proxying enable

[RouterB-Ethernet1/1] quit

[RouterB] interface ethernet 1/2

[RouterB-Ethernet1/2] igmp enable

[RouterB-Ethernet1/2] quit

Verifying the configuration

# Display the IGMP configuration and operation information on Ethernet 1/1 of Router B.
